As long as it does not disrupt mIRC performance.
However I believe it is unnecessary because it is possible to get satisfactory results with /timer.
Exemple: /haddz HASH ITEM N
alias haddz {
hadd -z $1-
.timerhaddz $+ $ticks $+ $rand(111,999) 1 $3 unsethash $1-2
}
alias unsethash {
if ($hget($1,$2)) .timerhaddz $+ $ticks $+ $rand(111,999) 1 $v1 unsethash $1-2
else {
; Unseted hash item
echo -s unset item $2 on hash $1
}
}
